From the images you sent I got the impression that you have multiple series in your chart that are not using stack mode.
When you have multiple series which are not stacked with specific stackMode you should have in mind the order in which you are adding them to the chart. The first series to add will be drawn at the bottom, that is why the yellow and the orange series are not visible on iOS, their graphics come lower than the blue and the green series so they remain hidden behind them.

Consider adding the series in different order so that the ones with lower values appear on top (to be added last).

In case this does not help you, please, write back any time.

I can see that you are applying stack mode but in the images the chart appears as stack mode is not applied both for Android and iOS.
Could you please send us a sample project showing the described behavior, because we are not able to identify the issue just from the code snippet.

Thank you for your cooperation.

After some time spend digging we have concluded that the iOS chart indeed has an issue with the rendering of multiple series in stack mode. The issue is basically that every new-added series is rendered right on top of the previous in other words it is covering everything added so far.
In Android every new-added series is rendered behind the previous so there is no overlapping between the series and every series is visible.

I am pasting a snippet of your series, the only difference is that the color palettes are removed, this way the chart uses it's default colors which are transparent. I believe it is easier to see the issue I am trying to explain. When you run the project you will see that the series are rendered correctly as data values and that all of them are presented but every new-added is covering the previous. Please, copy the snippet and run your project with it.

We will investigate in depth this behavior and will estimate a fix for it.
Thank you for your cooperation and pointing us to this issue in the chart.
I am adding 800 Telerik points for bringing this to our attention.

Dear Sophi,
Do you have any estimation about when this problem
will be fixed?
Our customers are asking for an iOS APP, and it is
crucial for us to have it ASAP.
Even if you have a Beta Version with
this BUG fixed would be OK for us.
Thanks for your effort.
Regards.

Sophi

We are currently occupied with tasks, so will be able to include this issue probably in our next iteration.
As a rough estimation for the fix I would say the middle of November.
We will get in touch with you when the fix is available.
